After enjoying success with his original VW-powered Sonerai, John Monnett decided to develop the Sonerai II, a tandem-seated version. Both pilot and passenger sit under a bubble canopy which is hinged on the right side. The Sonerai II differs mainly by being slightly larger, making use of a more powerful engine, and by being stressed for aerobatics when flown by the pilot alone.

Sonerai IIL

The II-L is the same aircraft but with a "low-wing". The low-wing version is especially popular with 6 foot plus pilots, as the pilot legs go over the main spar carry through structure.

The Sonari II was also available as a low-wing nose gear two place, or the Sonerai II-Stretch: A low-wing model 18" longer than the original, as a low-wing taildragger and a low-wing tri-gear. The Sonerai II-LT is the steerable nose wheel version.

The Sonerai II series will accept VW power plants from 1700cc - 2276cc.

Price in 1982: $2,742 (Excludes engine).

All models of the Sonerai II use a minimum of different sizes of materials to reduce the cost, without hampering the integrity of the design. The wing is all aluminum and is composed of two panels that easily fold along side the fuselage enabling the Sonerai II, II-L and II-LT to be towed tail first on its own gear. Stainless steel cherry rivets are used to skin the wing. The fuselage and tail surfaces are constructed of standard sizes of 4130 steel tubing that are fabric covered. All aluminum sheet used is 2024-T3 .025" except for the spars which are .040".

The fiberglass cowling removes easily to allow complete access to the engine, magneto, tank and instruments. The landing gear is a formed aluminum spring with 5" wheels and 3/4" axles. A tapered tailspring rod is used for the tailwheel (II and II-L) All Sonerai II's feature a l0 US gallon main tank with the option of a 6 gallon auxiliary tank carried on the passengers floor board (without passenger).
